+ripped from Debian
+
+this change was made to generic __nexttowardf, but not the long double version
+
+2008-05-05  Aurelien Jarno  <aurelien@aurel32.net>
+
+	* sysdeps/ieee754/ldbl-128/s_nexttowardf.c: Include float.h.
+	(__nexttowardf): Use math_opt_barrier and
+	math_force_eval macros.  If FLT_EVAL_METHOD is not 0, force
+	x to float using asm.
